Message Box Asking Wether The User Wants To Save Before
FormClosing and Application.Exit is causing the MessageBox to c#
MessageBox Issue Windows Forms Application C#
How can I prevent window closing by showing a MessageBox ? Show( "Do you really want to close? Do you want to save before exiting? Visual C#
Show("Do you really want to close the program?", "SomeTitle", MessageBoxButtons.YesNo); if (dialog == DialogResult.Yes) { Application.Exit()

[@jepkenept6746]

Instead of writing application.exit(); use e.cancel=false; you wont need to double click yes! hope this helps

[@imPymo]

Jep Kenept Thanks. :D

[@jepkenept6746]

Jonathan No problem, glad that i could help.

[@markpace123]

Jep Kenept Works :D thank you!

[@chintangotecha7089]

Jep Kenept It works well, thanks a ton

[@jepkenept6746]

Mark Pace :) your welcome. Happy Coding.

[@whyisthishandletaken]

Thank you. ProgrammingKnowledge should take your response as it sorts out the program

[@GIDEONKIMATHI]

Application.ExitThread() works fine.

[@Makeforfun18799]

clear and easy to understand me.thanks

[@cyberpunk_42]

just get rid of the first IF for the YES option :) ...if you then save it and click on yes it closes the application anyways, and the NO option works as intended... hope it helps its the easiest way...

[@jjstairs]

If you want to fix your code so the message only shows once replace "Application.Exit();" with "this.Dispose();". It fixed the issue in my program.

[@theCEO-e9f]

instead of using Application.Exit(); you can also use there e.Cancel=false;

[@TripleForce]

sorry guys... I already solve the e.Cancel error and is now OK... I did mistake of putting the code in the different procedures... my bad... thanks ProgrammingKnowledge for this code....

[@serique1323]

There in your tutorial Form1 - .Hide and it is in RAM. WHen you close 2nd form - programm asks 2 times for closing - 1st time for Form2 and second time for Form1. How can i "kill" form1 and get only 1 message "Are you sure want to exit" instead of 2?

[@kevinkastrowiak]

exciting ! ! thanks fella ! !

[@PCGaming300]

How do you make it so that it asks if you want to save your work before closing the program?

[@soyal24]

tnx bro i used it to Delete button "r u sure u want to delete"

[@UMARBASHIR]

Use it Application.ExitThead();

[@mohamedahmedhamud4279]

yes my brother thank you first i need c# tutorial 1upto last how can i get sorted tutorials thanks a lot

[@sandeepscs]

e.cancel is not available? what do do? e.CloseReason only?

[@philipm1896]

processes.kill() stops everything imediately instead or .exit() which is a request or .close()

[@DavidAshby1]

How would you make this a class so that if your application had multiple forms you could reuse the same code rather than wasting a lot of time repeating the code in each form? Thanks

[@a.n.7338]

guys i am having problem when saving my c# application it is giving error of some kind i have to make project and have to save it to later connect to mysql i don"t know what to do??

[@cutipets8706]

Application.ExitThead(); works fine.

[@magnumsars]

Its asks 2 times when i click yes. why is that ? can you help me ?

[@Junaidlahori]

jst remove if for the application exit and use the cancel codes.which shown in video and its done.

[@slodkigrejpfrut]

Why do you upload the video with code that doesn't work as it should? You should wrote in the comment that this solution doesn't work well....:/

[@buengi-wn3nt]

private void Form_Main_FormClosing(object sender, FormClosingEventArgs e) { DialogResult result = MessageBox.Show("EXIT?", "Exit Program", MessageBoxButtons.YesNo); if (result != DialogResult.Yes) { e.Cancel = true; } }

[@lifestyle_]

e.cancel is not working ... please could you help me???

[@xchgamer]

Just copy this: DialogResult dialog = MessageBox.Show("Do you really want to close this application?", "Exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question); if(dialog == DialogResult.Yes) { Application.ExitThread(); } else { e.Cancel = true; }

[@nghiatran5834]

thank you for your clip

[@WennieBoy01]

yeah it really help

[@TripleForce]

anyone can help me.. this application.exit(); work fine but e.Cancel is not...error - it says "does not contain definition"

[@This1Guy1979]

Rodoon Pocson Be sure to double click on form closing, not form closed from the event list.

[@xchgamer]

So you have the "FormClosingEventArgs e" in arguments?

[@FleynSoft]

thank you =)

[@synapsefn3283]

"dialog" is an error :/

[@kingluther2365]

The Problem is this code (dialog == DialogResult.Yes) Try this (dialog != DialogResult.Yes)

[@junreyongcol]

yes this seems the better idea. salamat tol

[@iProCombo]

Watch 1.5x speed

[@shoaibmehmood7339]

Use this method : Application.ExitThread();

[@dbs03075]

I love you

[@jansmcwyn2870]

my visual studio is 2010 but the e.cancel not works..

[@TheElectricCherry]

Jans Mcwyn Cunanan mine is 2015 (I think) and it still doesn't work

[@higsonS2]

It work

[@malohtie]

dont need tu use application.exit();

[@TheElectricCherry]

e.Cancel = true; isn't real

[@ahmedsalah2662]

Application.ExitThread() works fine.

[@hardip5523]

This works great, and it's only a few extra characters compared to a whole different method! Thank you for sharing!

[@abodesegunezekiel6145]

Thanks Mr Ahmed i cannot but testify that it Works
